Letters Patent No. 94,377, dated August 31, 1869.

IMPROVEMENT IN STEAM-HEATER.

The Schedule referred to in these Letters Patent and making part of the lame.

castings, AA, 850., which, when put together, form the water-space, steam-space, fines, and fire-box.

These castings are made independent, and remain so, even when put together,with the exception of a steam-connection, B, near the centre and top of the steam-space and water-connections G and O, in front and rear of the fire-box below. These steam and water-connections are suitably packed at the joints to prevent escape.

The castings are placed vertically and longitudinally. They are hollow inside, and the water-spaces and steam-spaces are so formed. The fines, however, are formed by the contiguity of the castings, each casting having half fines on each side. Any number of layers of fines may, he nsed, althongh I generally use two, as shown in the drawings; flues D extending from thefire-box back to a rear connecting-chamber, E, and then from this chamber through the heater to the chimney F which is in front.

The chamber E has a trap or slide at the bottom at G, wherebythe ashes may be cleaned'out.

The main steam-pipe H may be attached to either side or to the top of the heater, as may prove most convenient.

.By this means I obtain a simple, compact, and inexpensive heater, one having a great amount of heating-surface and not liable to any explosion, or apt to get out of order through carelessness.

Having described my invention, I

WhatI' claim as new, and desire to secure by Letters Patent, is

The steam-heater herein shown, consisting of the upright castings A A, &c., constructed and arranged together as shown, each casting being formed with steam and water space within, and half fines at each side, substantially as herein set forth and described.
